I contacted someone and they said that the "No Service" is because of the fact that I missed something when I doing the unlocking. He told me that I had to replace the corrupted software by extracting the lastest 1.02 firmware and replacing the corrupted one. Anyone have any clue how to replace corrupted firmware/files? I am using a MAC by the way.

Connect to iTunes, click on the iPhone tab.
Click "Restore".
This will restore it to a back up from the previous sync.
If u synced after u messed up in doing the unlock, then u need to go download the firmware. MMi has it here, in the download/firmware section.

After which, you can attempt to perform the unlock again.
Heads up though, future iPhone updates could re-lock the phone, or mess up your iPhone, forcing u to do a restore.

This is due to the methods which current software unlock solutions use.
